Realflight Simulator
Instructions on how to run
Open RealFlight Evolution
Changing the Aircraft/Airport settings:
Press Escape → Free Play → Aircraft → Quadcopter X - flightaxis (If you don't see this file go to step 3), press Select.
Press Escape → Free Play → Airport → Eli Field → Select → Fly.
If you completed step 2 successfully you can skip to step 4.
Download the QuadcopterX model from here: https://github.com/ArduPilot/SITL_Models/blob/master/RealFlight/Released_Models/Multicopters/QuadCopterX/QuadcopterX-flightaxis_AV.RFX
Once downloaded, press Escape → My RealFlight → Import → RealFlight Archives → select the file that you just downloaded and press Open.
A message, “..was successfully imported” should be displayed. You can now complete step 2.
Press Escape → Settings → Physics → Quality → RealFlight Link Enabled and make sure it is enabled, and press Select.
In the same menu, go to "Pause Sim When In Background" and "Pause Sim When In Menu" and make sure they are both disabled.
In Settings, go to Graphics → Quality → Graphics Presets, set it to Low and Apply. Restart RealFlight Evolution if needed.
Open Mission Planner.
In the SIMULATION tab, change the Model to "flightaxis" from the drop-down menu and press Multirotor (with the Stable version). Make sure that Realflight is not in the pause menu when doing this, otherwise you will time out without connecting.
Uploading waypoints/mission to Mission Planner:
Press Ctrl+F → Mavlink → set the first drop-down to TCP Host - 14550, check the "Write access" checkbox and Connect. Set the port to 14550 and press OK.
Run the pathing repository code with the command
python -m path_2023.Scan the QR code.
The script should run successfully (The script should output “Done” to signify it has finished). Go to the PLAN tab and press Read.
Open the CONFIG tab, go to "Planner" and change the Layout to Advanced.
Download the parameter file for the Quadcopter-X model from here: https://github.com/ArduPilot/SITL_Models/blob/master/RealFlight/Released_Models/Multicopters/QuadCopterX/QuadCopterX.param
In the CONFIG tab, go to Full Parameter List → Load from file → select the parameter file that you just downloaded and press Open.
You may get a number of pop-ups saying the values are out of range/marked as read only. Select Yes/Ok to all of them, then press Write Params.
Go to the DATA Tab → Actions and then press Arm/Disarm. Then select Auto, and make any input to the controller (e.g, moving the stick up and back down).
RealFlight should now execute the mission. You can press Arm/Disarm again if you want to force stop the mission, and spacebar to reset the vehicle's position.
Testing Status
The code has been tested and the pathing repository works as expected.
USB Communication
Instructions on how to run
Find a USB-C to USB-A cable
Connect the USB-C end to the Pixhawk. There is a USB-C port on the side of the Pixhawk.
Connect the USB-A end to a USB port on the ground station computer.
Power the Pixhawk

...
.
Determine the name of the COM port the Pixhawk is connected to on the ground station computer.
Edit the
CONNECTION_ADDRESSconstant in themain_2023.pyto be"comX"where X is the COM port number.For example, if the Pixhawk is connected to COM port 6 then the
CONNECTION_ADDRESSwould be"com6". The documentation for this can be found here: https://dronekit-python.readthedocs.io/en/latest/guide/connecting_vehicle.html#get-started-connecting under the “Connection string options” header.
Run the pathing repository with the command
python -m main_2023.Scan the QR Code.
The script should run successfully (The script should output “Done” to signify it has finished).
Remove the USB cable from the Pixhawk and place the UAV in position for takeoff.
Open Mission Planner and connect Mission Planner to the drone.
Press the “Plan” tab in the top left corner.
Click on the “Read” button on the right-hand side.
The waypoints from the script should appear on Mission Planner.

Testing Status
The code has not been tested and needs to be changed in order for successful upload of waypoints. The issue stems from the wait_ready() function in the dronekit library. ELRS is not able to upload the waypoints within the timeout and the function throws an exception. Need to specify a larger timeout to all calls of wait_ready(). Need to create a configuration file to specify the timeout value.
